Interpolation techniques for ray-tracing models

In numerous radio-communication applications, the knowledge of the electric al field along a given path is required. In urban environments, at high fre quencies, the study of the field values is a time-consuming process. In ord er to accelerate this task, two interpolation methods for an approximate an d fast evaluation of the field are presented. (C) 2000 John Wiley & Sons, I nc.
